Hibiscus plant named: ‘Little Prince’

ABSTRACT

A new and distinct cultivar of winter hardy hibiscus plant named ‘Little Prince’ is the result of a unique hybridization. This new and distinct cultivar is characterized primarily as to its novelty by its extreme cold hardiness to Zone 4, large tri-colored, purple-red-pink, thick textured flowers and its “Maple-shaped” foliage with a purple coloration, compactness of approximately 2½ feet, its vigorous and uniform breaking habit and its floriferous nature from midsummer until frost.

Latin Name: Hibiscus moscheutos×H. coccineus.

Varietal denomination: ‘Little Prince’, hardy Hibiscus.

FIELD OF THE INVENTION

This plant, as a hybridized hardy Hibiscus, is valuable to the landscape market for its improvements in thicker textured and brightly, tri-colored flowers and buds, refined “maple-like” foliage with a purple-green color, its all-around vigor, good compact breaking action, and adaptation to extreme environments, including the ability to consistently survive winter temperatures of at least −30 degrees Fahrenheit.

BACKGROUND OF THE NEW PLANT

The new plant of this invention is the result of a unique hybridization, with the breeding achievement being evidenced in the outstanding combination of characteristics exhibited by this new and distinct Hibiscus plant , which include:

-   -   (a) Refined, 3-5 lobed “maple-shaped” leaves with a slight         purple-green color and relatively smooth margins which combined         compliments the landscape;     -   (b) Medium to large-sized flowers that are outstanding for their         purple and pink colored, heavily speckled petals;     -   (c) The plant being very floriferous with flowers that stay open         for at least one to two days;     -   (d) The plant being small but vigorous with compact and uniform         breaking action which gives it unique landscape utility; and     -   (e) The plant being so hardy that it can consistently withstand         winter temperatures of at least −30 degrees Fahrenheit.

SUMMARY OF THE INVENTION

‘Little Prince’ was the result of a 50-year breeding program. Its ancestry includes Hibiscus moscheutos and Hibiscus coccineus. More specifically, the plant resulted from multiple crossings with an unnamed, Fleming-bred Hibiscus moscheutos (non patented) and an unnamed Fleming-bred Hibiscus coccineus (non patented). The seedling which most nearly met all of the above standards was selected.

This new plant first bloomed in the summer of 2001 and was selected by Gretchen Zwetzig on her property located at 8101 S. 14th St. 68512 Lincoln, Nebr. (previous address for applicants). Asexual propagation of the plant by cuttings and root division in Lincoln, Nebr. has shown that the unique and distinguishing features of the plant are faithfully transmitted from generation to generation and appear to be fixed.

Since its origin, the plant has bloomed from midsummer until frost, while exhibiting the aforementioned distinctive characteristics. This hardy Hibiscus plant greatly contributes to the market with its, sheer beauty and utter refinement, its compact growth habit, its enhanced resistance to disease and insects, its stability through extremes in rain and drought, and its extreme hardiness.

BRIEF DESCRIPTION OF THE DRAWINGS

The flower and foliage of the cultivar at 2½ years of age are shown in the attached photographs.

More specifically, FIG. 1 is a close-up of the flower and the leaf.

FIG. 2 is a depiction of the whole plant.

The colors are as true as is reasonably possible to attain in photographic illustrations of this type. The colors illustrated may be slightly off due to light reflectance.

DESCRIPTION OF THE NEW PLANT

What follows is a detailed description of the new cultivar. The specific color descriptions are in accordance with The Royal Horticultural Society Colour Chart (2001), while general color recitations are consistent with ordinary American terminology.

‘Little Prince’ has not been observed under all possible environmental conditions. It is to be understood that the phenotype may vary significantly with variations in the environment such as temperature, light intensity, humidity, and day length without, however any difference in genotype of the plant. The following botanical characteristics and observations are gathered from the plant when grown in Lincoln, Nebr. (USDA Zone 4) and Lindsay, Calif. (USDA Zone 9).

THE PLANT

-   Parentage:     -   -   Seed parent.—Hibiscus moscheutos, unnamed and unpatented             Fleming-bred seedling.         -   Pollen parent.—Hibiscus coccineus, unnamed and unpatented             Fleming-bred seedling. -   Comparison between observed plant and parents: Parents were similar,     except for being approximately ½ foot taller in height than Observed     Plant and has less purple in the flower. -   Comparison between observed plant and other known cultivars: The     Observed Plant is unique, but most similar to ‘Fantasia’ U.S. Plant     Pat.
